1996 GT RTS-3

Recently got hold of a 1996 GT RTS-3, the shock and linkage are in good condition though there's a distinct 'knock' as the lower swing arm linkage returns to the main frame at the bottom bracket. Is this normal or is there some kind of rubber stop missing/deteriorated?

The £20 Barnsley one?

That’ll be the bushes gone. Very common.

Also check for cracks as it’ll likely have some.

It is. Where exactly are the bushes that would need replacing? The rear triangle as a whole doesn't feel loose. Fortunately no cracks found yet.

Lower linkage usually.

I had the exact bike in 1996 and it needed them about every 2 months.

I am not sure about bushings in the lower linkage, afaik it's bearings down there, 4x in the rocker. The bearings in there may need replacing.

Depending on the frame, you may have a top hat bushings or bearings in the main frame pivot that could need replacing.

Bushings at the drop out linkage.

It's worth trying to manipulate things by hand to see if there's any play anywhere.
